The study explored the therapeutic potential of human induced pluripotent stem cell-derived melanocytes (hiMels) for autologous transplantation in vitiligo patients. Researchers generated hiMels using a three-dimensional system that enhanced differentiation efficiency, showing characteristics similar to human epidermal melanocytes and involvement in vitiligo-associated signaling pathways. In vivo experiments demonstrated that MITF+PAX3+TYRP1+ hiMels localized in mouse hair bulbs and epidermis, producing melanin for up to 7 weeks post-transplantation. Additionally, MITF+PAX3+TYRP1- hiMelanocyte stem cells integrated into bulge-subbulge regions. These findings indicated that hiMels could reconstitute pigmented hair follicles and integrate into normal regions, offering a potential personalized cellular therapy for depigmentation disorders.
